A long-suppressed report by the Central Intelligence Agency's inspector general to be released next week reveals that CIA interrogators staged mock executions as part of the agency's post-9/11 program to detain and question terror suspects, NEWSWEEK has learned. The report describes how one detainee, suspected USS Cole bomber Abd al-Rahim al-Nashiri, was threatened with a gun and a power drill during the course of CIA interrogation. Nashiri's interrogators brandished the gun in an effort to convince him that he was going to be shot. Interrogators also turned on a power drill and held it near him. The purpose was to scare him into giving [information] up," said one [source]. A federal law banning the use of torture expressly forbids threatening a detainee with "imminent death." The report also says ... that a mock execution was staged in a room next to a detainee, during which a gunshot was fired in an effort to make the suspect believe that another prisoner had been killed. The inspector general's report alludes to more than one mock execution. Before leaving office, Bush administration officials confirmed that Nashiri was one of three CIA detainees subjected to waterboarding. They also acknowledged that Nashiri was one of two Al Qaeda detainees whose detentions and interrogations were documented at length in CIA videotapes. But senior officials of the agency's undercover operations branch, the National Clandestine Service, ordered that the tapes be destroyed, an action that has been under investigation for more than a year by a federal prosecutor. The new revelations are contained in a lengthy report on the CIA interrogation program completed by the agency's inspector general in May 2004.
